A Richard Meier protégée designed the modern interiors of this converted Brillo factory in the Dumbo section of the borough

All but one of the 15 apartments in the swank conversion of a former Brillo factory in the Dumbo section of Brooklyn has been sold.

And the last unit, a three-bedroom penthouse with a large terrace and fantastic city views, will probably sell quickly.

“We’ve had several buyers circling,” Halstead agent Charles Homet said. “Three purchasers are getting their ducks in a row.”

So far, four owners have moved into the building and others are in the process of closing, Mr. Homet said. Final construction on a couple of the units should be finished in the next few weeks. “By the end of April, we should be completely closed.”

Developed by Megalith Capital Management and Urban Realty Partners, the building is a boutique condominium on a landmarked cobblestoned block in Dumbo.

The four penthouse units are on two new floors built on top of the original four-story factory.

Floor-to-ceiling glass curtain walls with north and south exposures in this penthouse, Unit 5B, bring in lots of natural light, and highly engineered sliding walls replace conventional doors in some areas of the apartment, allowing light to fill the entire home.

The apartment features seven-inch-wide radiant-heated prime-grade Siberian white oak flooring. The terrace is equipped with gas, water and electric hookups and offers vistas of the Brooklyn and Manhattan skyline, as well as the Manhattan Bridge.

The kitchen has a large pantry, refrigerator and wine cooler by Sub-Zero and range by Wolf. The countertops and backsplash are made of Montclair Denby marble, complemented by a polished-chrome Hansgrohe faucet.

A keyed elevator opens directly into the entry foyer of this three-bedroom, three-bath, 2,520-square-foot penthouse with a 785-square-footprivate terrace.

Design Pedigree

Gil Even-Tsur, the interior architect, “worked with Richard Meier and was one of the chief designers of the Meier buildings on the West Side Highway,” Mr. Homet said.

Amenities

Building amenities include a full time doorman, landscaped sunken garden, access to a private parking garage, a well-appointed gym and bicycle storage. A footbridge at the bottom of Jay Street leads directly into Brooklyn Bridge Park.

“Growth has really accelerated in the last three years, in a good way,” said Mr. Homet, an 11-year resident of Dumbo.

“Anything that can be converted has been converted or is in the process of being converted,” he said. “It’s very appealing to lower Manhattan buyers. We’re now getting these buildings that I think rival anything in Tribeca.”
